Admit it. At least once in your life, you have eaten a little more than you needed to. Obviously, eating too much is not ideal for our health, but everyone does it sometimes, and there are worse vices than eating an extra slice of pie, pizza or Thanksgiving turkey every once in a while.

Surviving a heart attack or heart procedure is not the end of the story.

After the damage a heart can endure through the course of heart disease, it needs to heal, and after a heart event or heart surgery, many medical centers recommend a supervised heart rehabilitation program to help in the healing process.

A heart attack does serious damage to the cells that drive the heart. Cells that would normally create new blood vessels and heal the heart often become useless scar-forming cells. UNC School of Medicine's Eric Ubil discovered a way to reverse this process, turning scar cells into blood-vessel builders and healing the heart in mice. Listen in as UNC-TV's Daniel Lane and Eric Ubil discuss this research, its significance and the next steps toward practical application for patients.
